How to Tell if Your Engine Oil Is Bad
While people seek San Ramon auto repair services for a variety of reasons—including check engine light diagnosis and brake and timing belt repair—one of the most common types of auto maintenance is an oil change. Fortunately, this process is very simple. Watch this video for a few tips on how to tell if your engine oil is bad.
A quick visual inspection should tell you much of what you need to know about your oil. If you can see your dipstick through the oil, it is still relatively clean; if the oil is opaque, however, it must be changed. Make sure that the scent of your oil resembles the scent of new oil from a can, and check the cap for white deposits that indicate the inability to absorb and dissipate moisture. You can also simply consider the last time you changed your oil, as it should be replaced every three to four thousand miles.
